Goodell's current contract runs through 2019 and pays him approximately $30 million annually. The 58-year-old has been commissioner since 2006.

All 32 NFL owners voted in May to extend Goodell's contract and authorized the compensation committee to negotiate on their behalf.

Dallas Cowboys owner Jerry Jones - who's recently battled Goodell and the league over the suspension of Cowboys star running back Ezekiel Elliott - threatened to file a lawsuit if Goodell's extension is completed without final review or approval from the league's 32 teams.
